source: AggregationType
definition: Aggregation Type UN/CEFACT code list.
code list scope: domain
term status: proposed

Sum
type: Concept
definition: Values add up (e.g. total GHG emissions across all facilities = sum of each facility's emissions)
in scheme: Aggregation Type
notation: sum

Count
type: Concept
definition: The number of occurrences is counted
in scheme: Aggregation Type
notation: count

Maximum
type: Concept
definition: Only the largest value across the set is meaningful
in scheme: Aggregation Type
notation: maximum

Average
type: Concept
definition: Values are combined as an unweighted arithmetic mean
in scheme: Aggregation Type
notation: average

Weighted average
type: Concept
definition: Values must be averaged weighted by volume/output (e.g. emissions intensity per kg across suppliers)
in scheme: Aggregation Type
notation: weighted-average

Minimum
type: Concept
definition: Only the smallest value across the set is meaningful
in scheme: Aggregation Type
notation: minimum

Latest
type: Concept
definition: Only the most recent value is meaningful (e.g. a biodiversity assessment score where only the current state matters)
in scheme: Aggregation Type
notation: latest
